Just going off on a tangent from Michael's thread on converting a cat/small dog carrier to a parrot carrier, I was wondering what other people use.
I have tried a few now:
I have a homemade cage that the Amazon was shipped in. Very sturdy, but too heavy and hard to clean. I've kept it for emergency use.
I have the converted cat carrier, with a perch.
I have a Celltei 'Pack-O-Bird'. I love the way they look, but the birds don't like it very much...none of them. I think it's too hard for them to see out of. I also don't trust that they couldn't chew their way out in short order...
The best, although it's ugly, is the Avian Adventure backpack. It's essentially a smaller bird cage in a canvas covering. I tried to find a link, but I can't. I'm assuming they've gone out of business? The birds all like this cage. And I like that you can't accidentally open it - you have to take it off (your back), and open it from the back. Very safe.
